1. Tết Trung Thu in one answer

Tết Trung Thu is Vietnam’s Mid-Autumn Festival — a full-moon celebration of family, children and the harvest, held on the 15th night of the 8th lunar month. For a few weeks each autumn the whole country fills with mooncakes, star-shaped lanterns and the drums of lion dances, building to one luminous night when families gather, children parade with lanterns, and everyone eats mooncakes under the brightest full moon of the year.

Though it shares roots with the wider East Asian Mid-Autumn, Vietnam’s version has become above all a children’s festival (Tết Thiếu Nhi) — think lanterns, masks, toys, sweets and lion dances rather than anything solemn. For a visitor it’s wonderfully easy to enjoy: you don’t need tickets or a plan, just be in the right neighbourhood on the right night with an appetite for mooncake.

2. When is the Mid-Autumn Festival in 2026?

In 2026, Tết Trung Thu falls on Friday 25 September. The date moves every year because it follows the lunar calendar — always the 15th day of the 8th lunar month, the night of the autumn full moon. (For reference: it lands on 6 October in 2025 and 25 September in 2026.)

But the festival is really a season, not a single day. From late August, mooncake stalls appear on pavements, shops fill with lanterns, and companies send mooncake boxes as gifts. Lion-dance troupes start touring the streets a week or two ahead, and the busiest, most atmospheric evenings are the 13th, 14th and 15th nights of the lunar month — the days right before and on the festival. If your trip is anywhere near late September, you’ll catch the build-up even if you miss the exact night.

3. What actually happens on the night

Come the festival evening, neighbourhoods, old quarters and riverfronts come alive. The core of it is simple and joyful:

• The lantern parade (rước đèn) — children walk the streets carrying lit lanterns, singing festival songs. It’s the heart of the night and the reason the lanterns matter.
• The lion dance (múa lân) — troupes of drummers and dancers in lion costumes perform outside homes and shops for luck, led by the round, grinning Ông Địa (Earth God) mask.
• The offering tray (mâm cỗ) — families lay out a tray of mooncakes, seasonal fruit (pomelo, persimmon, banana), and sweets, often shaped into animals, to admire the moon. Later they “phá cỗ” — break it open and share it.
• Moon-watching — the whole point. Families gather outside, the children eat too many sweets, and everyone looks up at the year’s roundest moon, a symbol of reunion and completeness.

It’s intimate and domestic at its core, but in the lantern streets and old towns it spills into a public, switched-on celebration anyone can wander into.

4. Mooncakes (bánh trung thu)

If the festival has a flavour, it’s the mooncake. Bánh trung thu are dense, round cakes — the round shape standing for the full moon and family reunion — and they come in two great families:

Fillings range from sweet lotus-seed or red-bean paste to the much-loved savoury-sweet thập cẩm (mixed nuts, candied peel, sausage and seeds), usually wrapped around one or more salted egg yolks that stand in for the moon. They’re rich — a single cake is shared between several people with strong tea.

Mooncakes are as much about giving as eating: ornate boxes are exchanged among family, friends and businesses for weeks beforehand. You’ll see everything from humble street-stall cakes to luxury hotel boxes. Buy a box or a couple of cakes from a bakery (Kinh Đô and Bảo Ngọc are common brands; hotel bakeries do beautiful ones) — they make a great edible souvenir, and trying one is the easiest way into the festival. Pair it with Vietnamese food more widely in our Hoi An food guide.

5. The lanterns — đèn ông sao and friends

Lanterns are the festival’s signature image. The icon is the đèn ông sao — a five-pointed star lantern framed in bamboo and covered in coloured cellophane, carried on a stick by children in the parade. Tradition says the lanterns help Chú Cuội (the man on the moon, see below) see his way back to earth.

Beyond the star you’ll find lanterns in every form: carp and animal shapes, paper “pull lanterns” (đèn kéo quân) whose warm air spins a parade of shadow figures inside, modern battery-lit cartoon characters, and — in Hoi An — the famous silk lanterns in every colour. Buying a simple lantern for a few dollars from a street stall and joining the evening stroll is one of the loveliest, cheapest things you can do as a visitor.

6. The lion dance (múa lân)

Few sights capture the energy of Tết Trung Thu like the múa lân. In the days around the festival, troupes of young performers — one working the big-eyed lion (lân) head, another the tail, backed by a thundering drum and cymbals — dance outside homes and shops, where owners hang up “lucky money” for the lion to “eat” in exchange for blessings and a prosperous season.

Leading the dance is the comic figure of Ông Địa, the round-bellied Earth God in a smiling mask, fanning the lion and clowning with the crowd. It’s loud, acrobatic and joyful, and you don’t need to seek it out in the lantern districts — it usually finds you. Tip the troupe a small note if you stop to watch and film.

7. The legends behind the festival

Two folk tales give the night its meaning, and both are about the moon.

Chú Cuội and the banyan tree. Cuội was a woodcutter who found a magical banyan with the power to heal. Warned never to water it with anything unclean, he one day returned to find his wife had broken the rule; the tree tore loose from the earth and rose into the sky, with Cuội clinging to it, all the way to the moon. On a clear Mid-Autumn night, Vietnamese say you can see Chú Cuội sitting under his banyan tree up there — and children’s lanterns are lit to help him find his way home.

Chị Hằng, the Moon Lady. Hằng Nga, an immortal fairy, is said to live on the moon; in modern celebrations a “Chị Hằng” and “Chú Cuội” often host children’s events, hand out gifts and lead the songs. Together they make the moon — and the festival — a story children grow up inside.

8. Where to experience Tết Trung Thu

The festival happens everywhere, but a few places do it spectacularly. If you can choose where to be on the night, choose one of these.

Hanoi — the Old Quarter & Hàng Mã street

Hàng Mã street 📍Map in the Hanoi Old Quarter is the country’s most famous Mid-Autumn scene: a tunnel of lanterns, star masks, drums and toys, packed with families for weeks beforehand. Nearby Lương Văn Can street and the Phùng Hưng mural arches add to it. It’s free, photogenic and full of lion dances after dark.

Hoi An — lanterns on the full moon

Because the festival falls on a full moon, Hoi An 📍Map is at its most magical: the old town dims its electric lights, thousands of silk lanterns glow, and visitors set floating candle lanterns adrift on the Hoai River. It overlaps with Hoi An’s monthly Lantern Festival, so the Mid-Autumn full moon is the biggest lantern night of the year. A short Da Nang or Hoi An trip times beautifully around it.

Ho Chi Minh City — Chợ Lớn & Lương Nhữ Học street

In the Chợ Lớn (Chinatown) district, Lương Nhữ Học street 📍Map overflows with lanterns, masks and lion heads, and the lion-dance scene here is among the liveliest in the country.

Tuyên Quang — the giant-lantern parade

For something unique, the small northern city of Tuyên Quang 📍Map throws Vietnam’s biggest Mid-Autumn parade, with enormous handmade model lanterns — some as big as a bus — wheeled through the streets. Locals call it the “City of Festivals” for good reason.

Hue, Da Nang and most towns hold their own celebrations too — wherever you are, head for the old quarter or riverfront after dark.

9. Is it a good time to travel to Vietnam?

Yes — with eyes open. Because Tết Trung Thu is not a public holiday, it doesn’t bring the closures or the travel chaos of Tết (Lunar New Year). Shops, sights, restaurants, trains and flights all run as normal, prices don’t spike, and you simply gain a beautiful cultural layer on top of your trip.

Late September weather is mixed: the north (Hanoi) is pleasant and cooling, while central Vietnam (Hoi An, Da Nang, Hue) is in its wetter season with a real chance of rain or storms — check the forecast and keep the Hoi An lantern evening flexible. For the seasonal picture, see our best-time-to-visit guide, and to plan the wider route, our Vietnam travel guide and Northern Vietnam guide.

10. How to join in as a visitor

You don’t need a ticket or a tour — the festival is open and street-level. A few easy ways in:

• Buy a lantern. Pick up a star lantern or a silk one from a street stall for a dollar or two and carry it on the evening stroll. Instant participation.
• Try a mooncake. Buy a single cake or a small box from a bakery and share it with tea — the taste is the festival. Savoury thập cẩm and lotus-seed are the classics to start with.
• Find a lion dance. Follow the drums in the lantern districts after dark; tip the troupe if you film them.
• Be on a riverfront or in an old quarter. Hoi An’s river, Hanoi’s Hàng Mã, HCMC’s Chợ Lớn — the magic is concentrated in these spots on the 14th and 15th nights.
• Set a floating lantern in Hoi An, making a wish as it drifts off — touristy, yes, but lovely.

Be a gracious guest: ask before photographing children up close, tip lion-dance troupes, and don’t block family processions for a photo. A smile and a “chúc Trung Thu vui vẻ” (happy Mid-Autumn) go a long way. See our Vietnam etiquette guide for more.

11. Mid-Autumn vs the Hoi An Lantern Festival

Travellers often mix these up, so to be clear: Hoi An holds a Lantern Festival every month, on the night of the full moon (the 14th day of each lunar month), when the old town switches off its lights for the lanterns. That’s a year-round monthly event — see our dedicated Hoi An Lantern Festival guide.

Tết Trung Thu is the national, once-a-year Mid-Autumn Festival in the 8th lunar month. In Hoi An the two coincide — the Mid-Autumn full moon is one of the monthly lantern nights, and the biggest — so visiting Hoi An on 25 September 2026 gives you both at once. Elsewhere in Vietnam, only Tết Trung Thu applies.

12. Practical tips for Tết Trung Thu

• Go in the evening, on the 14th or 15th. The festival is nocturnal; the two nights before the full moon and the night itself are the busiest and best.
• Buy mooncakes early. The best bakery boxes sell out in the final days; from early September choice is widest.
• Expect crowds in the lantern streets. Hàng Mã and Lương Nhữ Học get shoulder-to-shoulder — go a little earlier in the evening, and mind your belongings.
• Bring small cash. Lanterns, mooncakes, street snacks and lion-dance tips are all cash; see our Vietnam money guide.
• It’s great for kids. This is literally a children’s festival — lanterns, sweets and lion dances are a hit with families.
• Mind the central-Vietnam weather. If you’re banking on Hoi An’s river lanterns, keep a flexible evening in case of late-September rain.

Time a Hoi An itinerary or a Hanoi trip around late September and you’ll catch Vietnam at its most enchanting — lantern-lit, mooncake-scented and full of drums.
